CL Wrapper (GL): errors with Visual Studio 2005 / 2008 / 2010
Posted by Yoni Davidson, Last modified by Yoni Davidson on 27 December 2017 09:13 AM


The build fails with "CL Wrapper (GL)" error message.


This error message may be related to the IncrediBuild PDB file synchronization mechanism.


  1. On the machine hosting your main Coordinator, open up the Coordinator Monitor.
  2. Mark the initiator machine, or in the case of having more than one Initiator machines, use ctrl to mark them all.
  3. Right click and select "Set Registry Value"
  4.  Under the "Name" field please write: PdbForwardingMode
  5.  Under the "Data" field please write: 0
  6. Please perform a full solution clean and then rebuild the solution.

The PDBForwardingMode controls IncrediBuild's acceleration feature which basically treats pdb files in a different manner on each Agent in order to reduce the build time.
There is no effect on the build results by disabling this feature (In the registry set PDBForwardingMode=0) and the only effect might be slightly slower build times for Solutions that contain a lot of link steps.
